摘   要：从蒸压热平衡角度分析了B05级蒸压加气混凝土制品生产线的热耗和节能途径。结果表明，干密度每相差100 kg/m3，能耗相差16.5 kg蒸汽热能；坯体水料比每差1%，蒸汽能耗相差约1 kg/m3；与进釜坯体温度80 ℃相比，进釜坯体温度50 ℃，需多加蒸汽23 kg/m3，进釜坯体温度30 ℃，需多加蒸汽38 kg/m3；与蒸压釜初始温度70 ℃相比，冷釜升温（设20 ℃）需增加蒸汽量11.33 kg/m3，蒸压釜初始温度40 ℃，蒸压釜升温需要增加蒸汽量6.8 kg/m3；蒸压釜矿棉保护层厚度为200 mm和100 mm比较，蒸压釜散热损失使每m3制品减少约2 kg/m3；尾气排放热能相当于29.25 kg/m3蒸汽热能；每m3制品产生冷凝水热能为29.5 kg/m3蒸汽热能。
Abstract： From the view of thermal balance, the heat consumption and energy saving ways of B05 autoclaved aerated concrete(ACC) product production line are analyzed. The results show that when the dry density is 100 kg/m3, the energy consumption difference is 16.5 kg. The steam energy consumption is 1 kg/m3 when the water-solid ratio is 1%. Compared with the ACC body temperature of 80 ℃ before autoclave, if the temperature of the ACC body is 50 ℃, extra 23 kg steam is needed for 1 m3. If the temperature is 30 ℃, extra 38 kg steam is needed for 1 m3. Compared with the initial temperature of autoclave 70 ℃, if the cold autoclave temperature is 20 ℃, 11.3 kg steam is needed for 1 m3. If the temperature is 40 ℃, extra 6.8 kg steam is needed for 1 m3. Comparing autoclave mineral wool protective layer thickness of 200 mm with 100 mm, autoclave heat loss reduces about 2 kg/m3 of products. The exhaust heat is equivalent to 29.25 kg/m3 of steam. The heat energy of condensed water for product is 29.5 kg/m3 steam heat energy.
